Five Sweet Fat Bomb Recipes Under 2g Net Carbs

The ketogenic diet turns to fat for fuel when carbohydrate intake is sufficiently low. Fat bombs – high-fat, low-carb snacks – help maintain energy levels between meals while keeping carbs minimal. These five recipes use ingredients readily available at Tesco or Sainsbury’s, each containing under 2g net carbs per serving.

Why Fat Bombs Work on Keto

Research suggests that very-low-carbohydrate diets may help regulate appetite hormones like ghrelin (Sumithran et al., 2013). Fat bombs provide satiety without spiking blood sugar. At £0.30-£0.70 per serving, they’re cheaper than most keto-branded snacks.

Chocolate Peanut Butter Cups

Ingredients:

100g 90% dark chocolate (£1.80 at Sainsbury’s)
60g smooth peanut butter (no added sugar)
30g coconut oil

Melt chocolate with coconut oil, pour half into silicone moulds. Freeze 10 minutes. Add peanut butter layer, top with remaining chocolate. Makes 12 (1.8g net carbs each).

Lemon Cheesecake Bites

Ingredients:

200g full-fat cream cheese (£1.25 at Tesco)
50g butter
Zest of 1 lemon
1 tsp vanilla extract
30g erythritol

Mix all ingredients until smooth. Pipe into mini cupcake cases. Freeze 1 hour. Makes 8 (1.5g net carbs each).

Coconut Almond Clusters

Ingredients:

100g almond butter
30g coconut flour (£2.20 for 200g at Tesco)
20g chia seeds
50g coconut oil

Mix into small clusters. Chill until firm. Makes 10 (1.2g net carbs each).

What This Means in Practice

These recipes align with keto macro guidelines while accommodating British seasonal preferences – citrus flavours work well in summer, while spiced versions suit winter. Budget-conscious shoppers can find all ingredients at Aldi for under £10 total.

Raspberry White Chocolate Bombs

Ingredients:

50g cacao butter (£3.50 at Holland & Barrett)
30g freeze-dried raspberries
2 tbsp powdered erythritol

Melt cacao butter, mix with other ingredients. Pour into moulds. Makes 6 (1.6g net carbs each).

Salted Caramel Truffles

Ingredients:

100g macadamia nuts (£2.50 at Tesco)
2 tbsp caramel flavouring (sugar-free)
30g butter
Himalayan pink salt

Blend nuts into butter, add flavouring. Roll into balls, sprinkle with salt. Makes 8 (1.3g net carbs each).

Frequently Asked Questions

Can I use regular chocolate? Milk chocolate contains too much sugar. Opt for 85% cocoa or higher to stay under 2g net carbs per serving.

How long do these keep? Most fat bombs last 2 weeks refrigerated or 3 months frozen in airtight containers.

Are they suitable for diabetics? People with type 2 diabetes should monitor blood glucose response, as individual tolerances vary to sugar alcohols.

The Bottom Line

These five fat bomb recipes prove you don’t need sugar to satisfy sweet cravings on keto. Each provides energy-dense nutrition with minimal impact on blood sugar. If you’d rather not do the macro maths yourself, the Keto Dieting app does it for you on Google Play and the App Store.
